Where in the Bible does it say that the first 6 days of Creation were 24 hours long?

The focus is the first 19 verses of Genesis, Chapter One.

Notice there is no mention of light until verse 3:

(3) Then God said, "Let there be light"; and there was light.

(4) God saw that the light was good; and God separated the light from the darkness.

(5) God called the light day, and the darkness He called night And there was evening and there was morning, one day.

Okay, it says that God just created light and named the absence of it, darkness. Still no mention of Celestial Bodies providing territorial rule!

Verses 13-19,

(14) Then God said, "Let there be lights in the expanse of the heavens to separate the day from the night, and let them be for signs and for seasons and for days and years;

(In 14, it mentions the lights are to "seperate" day from night. And to be for "signs" for seasons, DAYS and years.)

(16) God made the two great lights, the greater light to govern the day, and the lesser light to govern the night; He made the stars also.

(In 16 the two great lights are created to Govern day and to Govern night.)

then...

(17) God placed them in the expanse of the heavens to give light on the earth,

(18) and to govern the day and the night, and to separate the light from the darkness; and God saw that it was good.

(19) There was evening and there was morning, a fourth day.

At best, not until the 4th day, is there mention of "governing bodies", which referred to the sun and moon. Up until know, God had asked the Earth to produce only vegetation. Not until verse 20, is there sign of "animal" life, (which is a subject for another question later).

So do you see what I'm saying?

It is not that Science is wrong (although it has been before), but our intepretations of what interpreted the length of a "day" and a "night" in the first verses of Genesis that have not been contemplated correctly!.

It is not until verse 16 through 18 that a design for distinguishing time (as we know it) is set in place.

Up until then, the length between Night and Day had not been defined.

So, the eath is billions of years old, the discoveries of science say so. And the Bible never said that the defined cycle of time being measured by the sun and moon began until the beginning of day 4! And the "heavens (Universe) and Earth" and "seed bearing plants" had already been created!
